Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592876, here are decompositions:

43 + 31592833 = 31592876
67 + 31592809 = 31592876
79 + 31592797 = 31592876
97 + 31592779 = 31592876
103 + 31592773 = 31592876
193 + 31592683 = 31592876
199 + 31592677 = 31592876
277 + 31592599 = 31592876

Showing the first eight; more decompositions exist.
